Caching and UAV Friendly Jamming for Secure Communications With Active Eavesdropping Attacks
نویسندگان
چکیده
In this paper, we discuss the security and reliability performance of a communication system, where base station (BS) transmits signals to multiple users an unmanned aerial vehicle (UAV) jammer sends friendly jamming protect against full-duplex active eavesdropper with aid caching. We derive closed-form expressions outage probability (OP) intercept (IP) for legitimate eavesdropper, respectively. Aimed at minimizing sum IP maximum OP among all users, jointly optimize BS transmit power, UAV location power. An efficient algorithm based on alternating optimization (AO) successive convex approximation (SCA) methods is designed solve problem. Numerical results show that compared other benchmark strategies, proposed solution improves caching jamming.

Overcoming Endurance Issue: UAV-Enabled Communications with Proactive Caching
Wireless communication enabled by unmanned aerial vehicles (UAVs) has emerged as an appealing technology for many application scenarios in future wireless systems. However, the limited endurance of UAVs greatly hinders the practical implementation of UAV-enabled communications. To overcome this issue, this paper proposes a novel scheme for UAV-enabled communications by utilizing the promising t...
متن کاملEavesdropping and Jamming Communication Networks
Eavesdropping and jamming communication networks is an important part of any military engagement. However, until recently there has been very limited research in this area. Two recent papers by Commander et al. [2, 3] addressing this problem represent the current state-of-the-art in the study of the WIRELESS NETWORK JAMMING PROBLEM. In this chapter, we survey the problem and highlight the resul...
متن کاملData-Aided Secure Massive MIMO Transmission with Active Eavesdropping
In this paper, we study the design of secure communication for time division duplexing multi-cell multi-user massive multiple-input multiple-output (MIMO) systems with active eavesdropping. We assume that the eavesdropper actively attacks the uplink pilot transmission and the uplink data transmission before eavesdropping the downlink data transmission phase of the desired users. We exploit both...
متن کاملWorst-Case Cooperative Jamming for Secure Communications in CIoT Networks
The Internet of Things (IoT) is a significant branch of the ongoing advances in the Internet and mobile communications. The use of a large number of IoT devices makes the spectrum scarcity problem even more serious. The usable spectrum resources are almost entirely occupied, and thus, the increasing radio access demands of IoT devices cannot be met. To tackle this problem, the Cognitive Interne...
متن کاملAnti-Jamming Frequency Hopping Techniques for Secure Multicast Communications
We address the problem of jamming mitigation of multicast communications in multi-channel ad hoc networks. Specifically, we develop two frequency hopping (FH) techniques for establishing multicast communications. These techniques, denoted by KFH and CFH, address the two following problems. First, establishing multicast communications in the presence of a control-channel jamming attack. Second, ...
